hi guys i am trying to make a switch case . however, the code i have involves a function calling other functions and so i cant create the switch. (when i create the switch and remove the function title for the subfunction, the main function cant run the case. for example:

function main 
for ...
        Y = EulerODE(tspan, Init,dt, Repressor, Vm(i), Kx(i));
        ...
            ...
            ...
            ...
end
...
    ...
    Y = EulerODE2(tspan, Init,dt);
...
end
%subfunction 1 
function Y = EulerODE(tspan,init,dt,Repressor,Vm,Kx)
...
end
%subfunction 2 
function Y = EulerODE2(tspan,init,dt)
end

Is there an error message? If so show us the full error message.

I assume that your problem isn't caused by the switch-statement. What happens if you comment out the switch-statement?

"and memove the function title for the subfunction" what exactly does that mean?

i havent actually made a switch because what ive tried isnt working. what ive written above works fine. basically i want to change what ive written in my question to something like what ive written below but i believe i cant have a function inside the switch? :

function main
switch 
case1 
    for ...
        Y = EulerODE(tspan, Init,dt, Repressor, Vm(i), Kx(i));
        ...
            ...
            ...
            ...
    end
    function Y = EulerODE(tspan,init,dt,Repressor,Vm,Kx)
    ...
    end
case 2
      ...
          ...
          Y = EulerODE2(tspan, Init,dt);
      ...
      function Y = EulerODE2(tspan,init,dt)
      end
end      %end switch
end      %ends function main

Hey Geoffrey,

Which version of MATLAB are you using? If you remove the main "function" declaration, it will consider the file to be a script. Local functions in scripts only started being supported in R2016b, so if you have a version earlier than that, then MATLAB will error. If you would prefer to use a script, you'll need to make separate function files for each of your local functions.

im using the online version of matlab, i have also the R2019b version. i havent actually made a switch because what ive tried isnt working. basically i want to change what ive written in my question to something like what ive written below but believe i cant have a function inside the switch? :

function main
switch 
case1 
    for ...
        Y = EulerODE(tspan, Init,dt, Repressor, Vm(i), Kx(i));
        ...
            ...
            ...
            ...
    end
    function Y = EulerODE(tspan,init,dt,Repressor,Vm,Kx)
    ...
    end
case 2
      ...
          ...
          Y = EulerODE2(tspan, Init,dt);
      ...
      function Y = EulerODE2(tspan,init,dt)
      end
end      %end switch
end      %ends function main
